新华社海南文昌2月12日电 题："为长征十号系列火箭首飞奠定重要基础"——访中国航天科技集团杨树 涛 新华社记者刘艺、黄一宸、刘一诺 长征十号低空演示验证飞行试验11日成功实施，承担着我国载人登月重任的长征十号系列运载火箭技术 验证箭亮相文昌航天发射场。 "这次试验，为长征十号系列火箭首飞奠定了重要基础。"在接受新华社记者专访时，中国航天科技集团 杨树涛表示，这枚火箭身兼三项使命：验证梦舟飞船上升段最大动压逃逸试验条件、火箭多级并联工作 的可靠性以及返回段相关关键技术。 长十系列火箭家族一员 长十系列火箭是为我国载人月球探测工程、空间站应用与发展工程而研制的新一代载人运载火箭，包括 长征十号、长征十号甲两种构型，分别为三级带捆绑式助推器、两级无助推器构型。 遵循循序渐进、逐步验证的思路，长十系列火箭围绕"一级动力系统性能验证+回收及重复使用验证"两 条主线，提出了"三级试车+系留点火+低空飞+技术验证飞行"四步走实施方案。 不同于常见的捆绑式火箭，执行这次任务的长十系列火箭技术验证箭，全长约55米，相较于系留点火试 验时"长高"了近30米。杨树涛介绍，这主要是因为增加了两部分结构，一是贮箱以上的过渡舱、舱间段 ...

首先，我们要看清这次试验的"考场"有多大。火箭要飞到100公里左右的最大高度，这个高度与未来正式任务中火箭一级的飞行状 态是基本一致的。这意味着，它是在最真实的空间环境里，同时解答几个"必答题"。 央视网消息：11日，我国在文昌航天发射场成功组织实施长征十号运载火箭系统低空演示验证与梦舟载人飞船系统最大动压逃逸飞 行试验。 中国载人月球探测工程迎来又一里程碑时刻——长征十号甲试验箭载着梦舟飞船，用"一次发射，完成两场大考"。那这两场大考， 考的是什么呢？ 这次试验核心就为了两件大事： ·验证未来载人飞船能否在火箭飞行最"难受"、最危险的那一刻，在最大动压点安全逃逸。 ·验证火箭怎么自己认路、精准返回，为重复使用铺路。 那什么叫"最大动压"？想象一下，你开车在高速公路上，把手伸出窗外。车越快，风压越大，手感觉越"重"、越"顶"。 火箭也一样！起飞后速度暴增，但空气还没那么稀薄，两者共同作用会产生一个压力峰值——这就是"最大动压区"。这是箭体 最"难受"，承受考验最严峻的时刻，而这个极限环境，在地面根本模拟不出来。 那这次试验，其实就是在最极端的时刻，模拟火箭出现故障，来检验梦舟飞船的逃逸系统能否立即启动，迅速带 ...

Core Viewpoint - The successful launch of the Zhuque-3 rocket marks a significant milestone in China's reusable rocket technology, despite challenges in achieving its expected payload capacity and issues with engine performance [1][11][29]. Group 1: Launch Details - On December 3, the Zhuque-3 rocket was launched from the Jiuquan Satellite Launch Center, successfully completing its flight plan and delivering a simulated payload into orbit [1]. - The first stage attempted a landing but experienced engine failure during descent, resulting in a crash approximately 67.2 meters from the intended landing zone [1]. Group 2: Development Background - Blue Arrow Aerospace, established in 2015, focuses on developing medium to large launch vehicles using liquid oxygen and methane as propellants, aiming to provide cost-effective and reliable launch services [3]. - The Zhuque-2 rocket, which successfully entered orbit in July 2023, was the first liquid oxygen-methane rocket to achieve this milestone, establishing Blue Arrow as a key player in the commercial space sector [3][4]. Group 3: Technical Specifications - The Zhuque-3 rocket features a diameter of 4.5 meters, a total length of 76.6 meters, and a launch weight of approximately 660 tons, with a low Earth orbit payload capacity of 21.3 tons [5]. - The rocket's first stage is equipped with four Tianque-12 engines, providing a thrust of about 900 tons [5]. Group 4: Challenges and Innovations - The Zhuque-3 rocket is constructed from high-strength stainless steel, which reduces manufacturing costs and enhances thermal resistance for multiple reuses [8][9]. - However, the rocket's first flight revealed issues with payload capacity, primarily due to the weight of the stainless steel structure, prompting design modifications to alleviate this problem [11][20]. Group 5: Future Prospects - Blue Arrow plans to enhance the Zhuque-3's capabilities with the development of the Tianque-12B engine, aiming for a thrust increase to 100 tons by 2027, which would significantly improve the rocket's payload capacity [23]. - The company is also preparing for future missions, including the launch of the Haolong-1 cargo spacecraft, which will further test the Zhuque-3's operational capabilities [23].
